Abstract

Disclosed is a composition for a Controlled Low Strength Material (CLSM) including cementitious materials, water, and fine aggregate. The cementitious materials include powdered basaltic lava and Ordinary Portland Cement (OPC). In the composition, the basaltic lava replaces some of the ordinary Portland cement in the CLSM as compared to a conventional CLSM. The basaltic lava replaces 25% to 90% of the OPC in a conventional CLSM. The CLSM can be used as a compacted fill for structural and non-structural construction applications.
